Two brothers, Mark and Charles, each inherit $30000. Mark invests his inheritance in a savings account with an annual return of

SVEN [57.7K]

Solution: Mark's initial amount $=30000$

Mark invest's his inheritance amount in savings account with an annual interest of 3.1%. Therefore, the Mark's interest amount after 1 year is:

$Interest = Principal-amount \times rate\times time$

$Interest= 30000 \times 0.031 \times 1$

$=930$

Therefore, total amount Mark will have after 1 year $30000+930$ =$30930

Now Charles also has $30000 from his inheritance.

Charles invests his inheritance in a CD paying 5.8% annual.

Therefore, interest amount for Charles after 1 year is:

$Interest = Principal-amount \times rate\times time$

$Interest= 30000 \times 0.058 \times 1$

$=1740
$

Therefore, total amount Charles will have after 1 year $30000+1740$ =$31740

Therefore, Charles will have $31740 - $30930 = $810 more than Mark

I need to multi-step function inverse, photo included

STALIN [3.7K]

Answer:

$f^{-1} = (9x + 1)^{7}$

Step-by-step explanation:

$y\:=\:\frac{x^{\frac{1}{7}}-1}{9}$

replace x with y:

$x=\frac{y^{\frac{1}{7}}-1}{9}$

solve for y:

$9x=y^{\frac{1}{7}}-1}$

$9x + 1 = y^{\frac{1}{7} }$

$y = (9x + 1)^{7}$

therefore:

$f^{-1} = (9x + 1)^{7}$
